FNHA-2-H-500.00
leached clear. The appearance is a bright silvery or light blue hue. The corrosion resistance is considered to be intermediate.
5.2.3 Specifications 86508315 through 86508322 (FNHA-2-H500.20 through .39): These specifications will consist of a zinc electroplate and a passivation treatment by a chromate coating. The 86508315 through 86508318 (FNHA-2-H500.21 through .29) appearance is yellow to brown including olive drab. The corrosion resistance is considered to be the greatest. 86508319 through 86508322 (FNHA-2H500.31 through .39) appearance is black. This black coloring of the chromate tends to reduce this coating’s resistance to corrosion.
2.
APPLICATION
This specification was released to define performance requirements for zinc electroplating where corrosion protection on ferrous surfaces are
5.2.1 Specifications 86508307 through 86508310 (FNHA-2-H500.00 through .09): These specifications will consist of a zinc electroplate without a passivation treatment. This electroplating appearance is bright silvery and will exhibit the least corrosion resistance. This process is also the least expensive.
1.2 This specification may involve hazardous materials, procedures and apparatus. This specification does not address the health and safety problems associated with its application or use. It is the specification user's responsibility to follow appropriate health or safety practices and determine the application or regulatory limitation prior to use.

MATERIALS / COATINGS
3.1 The dimensions specified on the drawing are before plating. If the application does not allow the additional thickness of plating, the actual required limits must be specified on the drawing and noted “AFTER PLATING”.
In addition to the above requirements, the plating specification shall be noted above the title block as shown in Figure 1. The part number shall be taken from Table 1. This number shall be matched with the numbers in Table 3 and the matching name will be used in the item name block as seen in Figure 1. The quantity shall be “0”.

The baking requirement shall be noted on Engineering drawings for parts having hardness greater than 34 Rockwell C or that are severely cold worked.
5.2.4 Specifications 86508323 through 86508338 (FNHA-2-H500.50 through .99): These specifications will consist of the same as above mentioned specification categories with the addition of a wax finish to alter the surface coefficient of friction.
3. DESIGNATION
The Engineering drawing or standard shall contain the following notation for the specification of zinc electroplating. Notion shall appear as noted below and in Figure 1.
5.2.2 Specifications 86508311 through 86508314 (FNHA-2-H500.10 through .19): These specifications will consist of a zinc electroplate and a passivation treatment by a clear or a colored chromate treatment
